6. **Choose a Font:** Tap on the font option to see a list of available fonts. Nova Launcher Prime allows you to choose from system fonts and also supports custom fonts that you’ve downloaded to your device. Select your desired font.
7. **Adjust Font Size (Optional):** Some launchers also allow you to adjust the font size of icon labels. Look for a font size option and adjust it to your preference.
8. **Apply the Changes:** The changes should be applied automatically. If not, restart your launcher or device.

**Adding Custom Fonts to Launchers:**

Nova Launcher Prime and some other launchers allow you to use custom fonts that aren’t pre-installed on your system. To do this, you’ll need to download the font file (usually in .ttf or .otf format) and place it in a specific folder on your device’s storage. Here’s a general guide:

1. **Download a Font File:** Find and download a font file that you like. Many websites offer free and paid fonts.
2. **Create a Fonts Folder:** Create a folder named “fonts” (or any name you prefer) on your device’s internal storage. You can use a file manager app like Solid Explorer or ES File Explorer to do this. Placing this folder in the root directory is usually the easiest to access.
3. **Move the Font File:** Move the downloaded font file into the “fonts” folder.
4. **Select the Font in the Launcher:** In the launcher’s font settings, you should now see the option to select the custom font from the “fonts” folder. In Nova Launcher Prime, you can access it via **Look & feel > Icon style > Label font**, then tap the plus icon to find and select your font.

**Advantages of Using Custom Launchers:**

* **Wider Font Selection:** Custom launchers typically offer access to a much wider range of fonts than built-in settings.
* **More Customization Options:** Launchers provide a greater degree of control over the overall look and feel of your device.

Substratum is a theming engine for Android that allows you to customize various aspects of your device’s appearance, including fonts. However, Substratum requires root access and a device that supports the Substratum theming engine. This method is generally more advanced and requires a deeper understanding of Android theming.

**What is Substratum?**

Substratum is a theming framework that overlays modifications onto your system without directly modifying system files. It uses a system of “overlays” that are applied at runtime, allowing you to easily enable or disable themes. Substratum requires root access to function properly because it needs to access and modify system resources.

**Requirements for Using Substratum:**

* **Rooted Device:** Your device must be rooted.
* **Substratum App:** You need to install the Substratum app from the Google Play Store.
* **Substratum Theme:** You need to find a Substratum theme that includes font options. Many themes are available on the Play Store or through other sources.
* **Device Compatibility:** Not all devices are fully compatible with Substratum. Check for compatibility issues before proceeding.

**Steps to Change Fonts Using Substratum:**

**Disclaimer: This example assumes you have already rooted your device and have a device compatible with Substratum. Proceed with caution, as using Substratum incorrectly can cause system issues.**

1. **Root Your Device:** Ensure your device is rooted.
2. **Install Substratum:** Download and install the Substratum app from the Google Play Store.
3. **Grant Root Permissions:** Open the Substratum app and grant it root permissions. The Superuser request dialog will appear; tap “Grant.”
4. **Install a Font Theme:** Find and install a Substratum theme that includes font options from the Google Play Store or another source. Make sure the theme is compatible with your device and Android version.
5. **Open Substratum and Enable the Theme:** Open the Substratum app and you should see the installed theme listed. Tap on the theme to open its settings.
6. **Select Font Overlays:** Within the theme settings, look for options related to fonts. These might be labeled as “Fonts,” “Font Styles,” or something similar. Select the font overlay you want to apply. You may need to select other overlays as well depending on how the theme is structured (e.g. SystemUI, Android System).
7. **Enable the Overlays:** After selecting the font overlay, tap the floating action button (FAB) at the bottom right of the screen. A menu will appear. Choose “Build & Enable.” Substratum will then compile and apply the overlays.
8. **Reboot Your Device (Optional):** In some cases, a reboot may be required for the changes to take full effect. The Substratum app will usually tell you if a reboot is necessary.
9. **Verify the Changes:** After rebooting (if required), check if the system font has been changed to your selected font.

**Advantages of Using Substratum:**

* **Advanced Theming:** Substratum offers a high degree of control over the appearance of your device.
* **Non-Destructive Theming:** Substratum uses overlays, which means it doesn’t directly modify system files, making it easier to revert changes.
